4 0

Answer: 10th Percentile

Step-by-step explanation:

The percentile of a variable in a dataset is the percentage position of the variable in the dataset such that the variables before this variable are below this percentage.

There are 20 variables in this data set and Biff scored a 65 which occupies the second and third positions on this dataset.

Picking the first position, 65 is the second variable in the data set so Biff's percentile is;

= Position on dataset/ No. of variables in data set

= 2/20

= 10%

= 10th percentile

A rope from the top of a mast on a sailboat is attached to a point 6 feet from the base of the mast. If the rope is 24 feet long

Zanzabum

Answer: It is about 23 feet.

Step-by-step explanation:

1. Let's call <em>x</em> the height of the mast.

2. You know that the rope is attached to a point 6 feet from the base of the mast and the rope is 24 feet long, therefore, you can draw the right triangle shown in the figure attached.

3. To calculate <em>x</em>, you must apply the Pythagorean Theorem as you can see below:

$x=\sqrt{(24ft)^{2}-(6ft)^{2}}\\x=\sqrt{540ft^{2}}$
